The name February comes from the ancient Roman Februarius. According to the Ancient Roman Calendar, February was the last month of the year, except when it was occasionally followed by Intercalaris, a month of variable length periodically added to the end of the year to keep the seasons properly aligned.

Some February Folklore

Borrowed Days
The days of February 12th through the 14th were said to be borrowed from the month of January and so it was expected that the weather should be cold and January-like. Stormy winter weather on these days foretold fair weather for the rest of the year.

But if these days are pleasant, or indeed if any days in February are too pleasant, it didn't bode well for the weather the rest of the year.

More weather lore

If the weather be fine and frosty at the start of February, there is more winter ahead than behind.

When the cat lies in the sun in February, she will hide behind the stove in March.

“If Candlemas Day be fair and bright,
Winter will have another flight
But if it be dark with clouds and rain,
Winter is gone, and will not come again.”

If Candlemas be fair and clear, there'll be two winters in the year.

And, of course, it takes a nice day for a groundhog to see his shadow.

A wet February, A wet Spring
